i would not defend Porsche on IMS related failures. It is obvious they have highly inconsistent reaction to dealing with such stuff - some people apparently get engine replacement covered, even if car is off warranty, other people get forced to pay 100% plus install charges, some get some 'discount' or forced to pay for install labor but not engine itself, it is pretty bad.

Check out issue 69 of Total 911 magazine (may still be on newstands in U.S.) - talks all about this issue - they project the IMS issue affects only 5% (at most 10%) of the models/year range with the M96/7 engines. Most cars that have the issue are driven at low RPMs and are low mileage cars, but there's no foolproof way to predict or categorize which cars will be affected.

GT- I have read in other threads that it is the low mileage, low rpm driven cars that are prone to IMS failure. Is there any reliable data that supports this or could it be hearsay? If Porsche won't release data on the number of failures how can we know any specifics on which cars failed?

My CPO'ed 05 base 997 was bought in 2008 with 36 K miles. After driving it an additional 300 miles the IMS went and I got a new engine.

He hasnt replied to any of the questions. Did you have the car serviced regulary? Did you contact the service manager and request Porsche look at the engine before you agreed to pay out of pocket? What is the actual story behind the car? Are you the original owner? Did you purchase from the dealer or private party? How many miles were on the engine when the IMS failed?
We have many questions before we can make any suggestions regarding your matter.

Can the articles in the Excellence and Total 911 be used to support the lawsuit against Porsche's troubled engine?

That's what I was thinking.. From reading both articles, it's obvious Porsche knows the problem exists, yet it appears they choose to fix the problem as it occurs. However, once you're out of warranty, it's a $10K service bill to get it fixed.

OP is probably gone but there's an extensive poll which is ongoing on www.rennlist.com in the 997 section.

Its hovering around 5% of owners who are actually on the forum. Mileage and other details are also being provided.

I just don't know how a luxury car brand such as Porsche who touts their engineering to be something special would let this continue in their cars. Money is the obvious one...who gives a S%*t about reputation....LOL.

Well, wouldn't a viable explanation of their behavior simply be that these aren't happening in a statistically significant number? One would think that as soon as these failures became commonplace they'd be forced to acknowledge it. That said, I'm not sure what the percentage cutoff is between insignificant and significant.

Given that people are getting $1.55 class settlements for Ticketmaster and $.05 for Ebay, you'd think there would be a viable class if these things were happening in numbers that are alarming. Right?
